mesa: Add SYSTEM_VALUE_VERTEX_ID_ZERO_BASE There exists hardware, such as i965, that does not implement the OpenGL semantic for gl_VertexID. Instead, that hardware does not include the value of basevertex in the gl_VertexID value. SYSTEM_VALUE_VERTEX_ID_ZERO_BASE is the system value that represents this semantic.
